found out my kenwood excelon kfc-595 headunit does not clip at all, unless i screwed something up.. but i checked it both ways it said i could... was actually able to turn my gain up.. although the clipping indicator was going crazy, idk what to believe. can the quality of the music make it clip even though the smd dd1 says it doesnt on just the test cd? cause i cant afford to replace anything else.. imma try the test at 40hz on the test cd tomorrow and see if it clips on the bass knob, then i know the knob is just not giving good reading, or the music is making i distort.
